I had just get Elastica from extension:elastica site, and cirrussearch from Extension:CirrusSearch.

I'm assuming i have ElasticSearch since the following is stated in my version:

ruflin/elastica

2.2.0

MIT

Elasticsearch Client

Therefore, i set the following from

$wgCirrusSearchServers = array( 'elasticsearch0', 'elasticsearch1', 'elasticsearch2', 'elasticsearch3' );

to

$wgCirrusSearchServers = "localhost''; 

There are other $wgCirrusSearch variables that you might want to change from their defaults.

Now run this script to generate your elasticsearch index:

 php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/updateSearchIndexConfig.php

 Once i run the updateSearchIndexConfig script, the following error shows:

content index...
Fetching Elasticsearch version...
Unexpected Elasticsearch failure.
Http error communicating with Elasticsearch: Couldn't connect to host, Elastic search down?

ANy idea what would cause this or how do i enable elasticsearch?

installed elasticsearch and works.

Hey how did you solve the problem -

Http error communicating with Elasticsearch: Couldn't connect to host, Elastic search down?

I think i got electricsearch working, but cirrus didn't work and i quit pursuing it.

Anybody has any luck? would be great if someone can post about it.

What version of Elasticsearch do you use? It seems CirrusSearch is currently working ONLY in ElasticSearch <= 7.10.x -> Check Extension talk:CirrusSearch

As of the release fo Elastica for MediaWiki 1.31.1, composer.json requires ruflin/elastica 5.3.0. However, that release uses a deprecated call to each(), which PHP 7.2+ catches. ruflin/elastica 5.3.2 has been released which replaces the deprecated call with other logic.

I have locally edited the composer.json file for this extension to update to elastica-5.3.2, and the problem goes away. i recommend all releases of Extension:Elastica which are supported on versions of MediaWiki which support PHP 7.2+ be updated to use ruflin/elastica-5.3.2 or better in composer.json.

Thank you Chiefgeek157 for sharing this helpful information to us!

Hi, When i using ruflin/elastica 5.3.0 return this error:

Deprecated: The each() function is deprecated. This message will be suppressed on further calls in /var/www/html/extensions/Elastica/vendor/ruflin/elastica/lib/Elastica/Multi/MultiBuilder.php on line 50

I have the same "deprecated call "error, does updating ruflin/elastica to 5.3.2 require reindexing? How exactly is that done?

How can I install this without composer, I am thinking that is my problem. I tried manually adding the lib folder to the extension directory, but this doesn't seem to fix it. I am on MediaWiki Version 1.31, with the latest Elastica. Here is my backtrace when trying to access Version special page:

any ideas?

Hi, I solved uninstalling elastic search, Elastica and CirrusSearch extensions and then following the instructions from the beginning. Everything works now. I guess it could be an issue after upgrading from 1.27.4 to 1.31.1 where another version of elasticsearch is used.

How can I debug the query from a search, to see if the client or the server or the query itself is not sending/receiving the right data? Everything in my setup seems right, but still no results at ANY search query are being received. I'm desperate. The issue comes from here: Topic:Uhko5f4mgr1nn3pt

Any tip will be thank.

If i use older require_once syntax, do i still need Composer?

According to my shell client, the install "failed with error". But the terminal output looks ok. Does it look like this install failed?

Can anyone help please?

The page says PHP 5.3+ works, yet when I run composer I get:

Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
 Problem 1
   - Installation request for satooshi/php-coveralls dev-master -> satisfiable by satooshi/php-coveralls[dev-master].
   - satooshi/php-coveralls dev-master requires php ^5.5 || ^7.0 -> your PHP version (5.4.16) does not satisfy that requirement.

... so "5.3+" is not accurate?

Which version of MediaWiki are you running? And more important, which version (REL1_2X) of the extension do you use, newer releases require newer versions of PHP.
